Cain: I think it's a sin because of my biblical beliefs and, although people don't agree with me, I happen to think that it is a personal choice.

Morgan: You believe that?

Cain: I believe that.

Morgan: You think people wait — you believe people get to a certain age and say, I want to be homosexual?

Cain: Let me turn it around to you. What does science show? Show me evidence other than opinion and you might cause me to reconsider that...Where is the evidence?

Morgan: You're a commonsense guy..You genuinely believe that millions of Americans wake up in their late teens normally and go, you know what, i kind of fancy being a homosexual? You don't believe that, do you?

Cain: Piers, you haven't given me any evidence to believe otherwise.

Morgan: My gut instinct, Herman, tells me that it has to be a natural thing.

Cain: So it's your gut instinct versus my gut instincts. I respect their right to make that choice. You don't see me bashing them. I respect them to have the right to make that choice. I don't have to agree with it. That's all I'm saying

Morgan: It would be like a gay person saying, Herman, you made a choice to be black.
